Hi Raskull, thanks very much for that, and for your timely response.
I now have the added fields appearing under an "Attributes" sub-heading at the bottom of the "Edit Event" page. Now to figure out how to get them to appear on the "front end"! Where is the best reference material for this plug-in, and is there a forum anywhere DEDICATED to Events Manager? I often find this WordPress.org support forum is so big that many questions get overlooked.
I have no problems with buying the Pro version just to get the developer's support, but I want to be sure this is the product I need before I fork out $75.
As one of my additional custom fields is "Web Link", do you know if there's a way to make that a clickable hotlink?
And, as an aside, what is the standard field "Region" for? By trying a few different countries, the Region drop-down only seems to get populated for the United States. I don't think I need it. Can it be removed from the "Edit Event" form?
Thanks again for your help.
